Hi, I recently got an Infinix HOT 3 LTE. It's a really great phone, but I have a problem with it, my 3G SIM card isn't working properly.
When I insert it and start the phone, the card is detected, I enter my PIN code, then when I try to make a phone call it says "Cellular network not available". I tried switching the SIM card slots, both didn't work for my card. Then I tried to change the network provider manually and all and I also tried changing other cellular network options over and over again but nothing worked, I also tried switching airplane mode on and off. I got frustrated with this problem and I decided to factory reset my phone, but the problem was still there. After that I tried using someone else's 4G SIM card, and it worked, so there's no problem with my phone or SIM slots. My 3G SIM card is fine I think, it works on my old phone, as well as others.
Please help if you can.

Greetings and welcome to assist. Are you sure the phone is compatible with your carriers bands? If you are sure try asking your network provider for a new sim
Good Luck

Hi,
I am unable to use 3G on htc desire. I have set the correct APN. The problem is that when I choose "WCDMA" as the network mode, it automatically switches back to "GSM only". The place where I live has no problem with 3G availability. I feel the problem lies more with my handset. Can someone please help ? Is there anything that I can do to get rid of this problem. My phone has lost its warranty since I unlocked it.
Have you tried any other operator sim card? It's a good troubleshooting to do when this kind of problems happen...
Had problems like that before and it was an incorrect APN setup.
Thanks for getting back. I tried with a different sim and a different operator. They were also not successful. APN setting is perfectly right for the current sim. The APN settings were given by the operator.

Are you using any kind of widget to switch APN on / off, 2G/3g ?... I noticed that for example, Widgetsoid can mess with 3g connection so much that sometimes you need to remove it and reboot the phone so you can get things working again.
Try using another SIM card too. It may give you a clue on what's going on: wrong settings / card with no data activated / etc ...
I am not using any widget to turn on/off the 3g. EDGE services work on my mobile while 3G is not working. If I use the sim card on to a different mobile, 3G works fine without any problem. Tried using another sim card with 3G data activated and that also did not work fine for me on HTC Desire.
I purchased a S6 on EE a week ago. Has been working fine with an ee sim, however I have not made any calls or texts yet, just using the phone for Internet on wifi etc.
I have a regular three sim which I would like to use so I have trimmed it down with scissors and this made me cut part of the gold contact bit off (I read online this shouldnt affect the sim).
I'm guessing this phone is locked as when I insert the sim it detects a new sim has been inserted, it makes me restart too. Upon booting up however it says no sim card/ emergency calls only however I see a solid connection. I cannot make any calls as it says not registered to a network or something.
Now my question is that is the phone picking up the sim card? If yes why is it not prompting me with a sim unlock code screen? Secondly is my phone not detecting the sim card at all? Is that the reason why I am not prompted with a unlock code screen? All help is appreciated. Thank you.
Go onto settings, then onto Mobile Networks, then Network Operators, then Search Networks then click the Three carrier. It will take a few mins to search for all the networks so do not back out.
I was traveling to and from US and India. 2 Days back when I entered London airport for US, my mobile did not show any signal what so ever. It was no service. It was working fine when i boarded the flight in US.
Now following things I have tried according to my knowledge
1. I tried disabling the sim card, changing from 2g-3g- 4g. No improvements.
2. I went to menu by *#*#4636#*#*, and trying radio on and radio off. Nothing
3. I suspected that antenna is damanged and it hardware problem.
4. But then this wired thing happend, while playing around when both the sim are active, I turn of the sim one, the mobile data is switched back to second sim. Then when i again switch back the sim 1, it is automatically configured for 2g. It gets signal, I can make calls and it works good. Moment I switch the mobile data to that sim the network vanishes and back to no service/emergency calls.
5. I figured that there is some problem with the sim, so I inserted that sim into old samsung grand mobile which 3G phone. It works flawlessly.
6. Tried other sims in the moto G, 4g dosent work for some sim cards.
7. By reading on I found that lot of people have this problem and have solved it by flashing firmware. I tried that too. Tried stock rom, new osprey 7.* Nothing seems to be working.
Any thoughts and comments are welcome. I am kind of frustrated by this small bug. Might be lapse on motolora part. If someone is still active in this community please help, reply.
hello, I have a Samsung s6 edge+ from sprint (SM G928P). It was working fine with all the carriers in my country (El Salvador) But after a Reset, it did not recognize any sim card. It shows a message saying to insert the UICC sim card provided by my carrier.
The weird thing is that, sometimes, it barely gets signal, but no data. This is just for a minute and then, no signal with any carrier.
Is there a solution? I have the MSL code in case I can use it. I tried to activate global mode , but it did not work.
thanks a lot in advanced
Could someone help me get cellular set up on my OP5t? I followed the guide, downloaded TWRP and LineageOS. For some reason my phone won't recognize the phone number on my SIM card. The SIM card's the right way up and my cellular date is turned on. I've tried resetting the APN settings. It's not a problem with the SIM card itself. I tried two, both of which worked in other phones, and even called AT&T support for half an hour.
